JPH0648404U - A ventilation device that can be opened and closed by a groove provided on the outsole of the boot - Google Patents

Abstract

(57) [Summary] [Objective] Ventilation grooves are provided in the front and back of the hard outsole that does not affect the strength or protection of the boot to prevent the feet from getting stuffy when wearing the boot. [Composition] The new air taken in from the ventilation groove 1 carved in the forehead of the hard outsole passes through the front ventilation hole 8 to the inside of the boot, and the next moist air inside exhausts the rear ventilation hole 9 Groove 2
It leaks to the outside via. When it is raining or when the function is unnecessary such as in winter, the ventilation plug can be stopped by inserting the opening / closing plug 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to preventing foot stuffiness when wearing boots, and more specifically, it relates to a ventilation hole in the outsole (4) and ventilation holes in the inner plate (5) and the insole (6) and opening / closing when unnecessary. It relates to the stopper (3).

[0002]

[Prior art]

 Conventionally, as a ventilation function for preventing foot stuffiness of boots, one in which a large number of small holes are formed in the upper (7) or an opening / closing device is attached is known.

[0003]

[Problems to be solved by the device]

 The upper (7) with functions and devices described in the prior art is easy to work but has a problem in the original foot protection of the boot.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, the ventilation groove (1) for intake is provided in the upper front part of the outsole (4) which is robust and has a considerable thickness, avoiding the upper (7) having problems of strength and weakness. Carve out, and carve out the exhaust groove (2) for exhausting air on the rear upper part of the outsole (4).

A front vent hole (8) and a rear vent hole (9) are provided in the middle plate (5) and the insole (6), respectively, as communication holes for the intake air to the inside of the boot.

[0006] During rain and winter, when this ventilation function is not required, the function can be easily stopped by inserting the front and rear opening / closing plugs (3).

[0007]

[Work]

 Fresh air taken in through the ventilation groove (1) enters the inside of the boot through the front ventilation hole (8). Exhaust is exhausted from the exhaust groove (2) through the rear ventilation hole (9) while mixing with the moist air that has stagnated in the boot. Therefore, the refreshing feel of the skin due to the decrease in humidity inside the boots and the feeling of ventilation can be obtained.

[0008]

【Example】

 Examples will be described with reference to the drawings. When the boot is worn, the air taken in through the ventilation groove as shown by the flow of the arrow in FIG. 5 circulates in the boot and is discharged through the exhaust groove (2).

When walking while wearing boots, the tilt from the toes of the foot to the heel acts as an on-off valve, and the ventilation from the shoe opening (11) is significantly increased as compared with the case where there is no ventilation function.

When the ventilation function is unnecessary, the function can be easily stopped by inserting the front and rear opening / closing plugs (3) into the ventilation groove (1) and the exhaust groove (2) as shown in FIG.

[0011]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

The strength of the boot is also excellent due to the ventilation function utilizing the outsole of claim 1 and the middle plate and insole of claim 2 and the three rigid bottom parts.

When the opening / closing plug according to claim 3 is used, it is only inserted into the ventilation groove and the exhaust groove, so that the operation is simple and the function can be stopped. In addition, the opening and closing plug is not conspicuous and does not hinder the external appearance.
